Portable vs. Fixed Gas Detectors: Which Is Right for Your Facility?

When it comes to protecting personnel and property in environments with potential gas hazards, choosing between portable and fixed gas detectors is a key decision. Each plays a distinct role in maintaining safety—whether you’re monitoring a confined space or keeping a production floor secure. Let’s break down the unique benefits of both types and how […]
The Cold Truth: Why Traditional Ammonia Sensors Fail – and How PureAire Leads the Way

The Cold Truth: Why Traditional Ammonia Sensors Fail – and How PureAire Leads the Way

Ammonia Detection in Cold Storage & Industrial Refrigeration-Challenges Ammonia is an essential refrigerant used in food processing, cold storage, and industrial manufacturing due to its efficiency and cost-effectiveness. However, detecting ammonia leaks in cold environments presents significant challenges. Many traditional ammonia sensors fail, provide inaccurate readings, or require frequent maintenance due to freezing conditions. PureAire […]
Chlorine Gas Spikes: Gas Detectors for Safety and Compliance

Chlorine Gas Spikes: Gas Detectors for Safety and Compliance

Chlorine Gas Spikes A chlorine (Cl2) spike is a sudden increase in the concentration of chlorine gas in the air, often occurring in water treatment processes or swimming pools. This spike can result from adding chlorine for disinfection or water chemistry fluctuations, potentially leading to elevated levels that may affect water quality and safety. Chlorine […]
Strengthening Air Quality Regulations: Colorado’s Efforts and National Trends

Strengthening Air Quality Regulations: Colorado’s Efforts and National Trends

Colorado is taking significant steps to improve air quality and protect public health by targeting five harmful air toxics: benzene, ethylene oxide, formaldehyde, hexavalent chromium compounds, and hydrogen sulfide. These air toxics, known to cause severe health effects like cancer and birth defects, will now be subject to state regulations under new guidelines adopted by […]

What is a Chlorine Gas Detector? Where is Chlorine Used and How to Protect from Exposure

Chlorine Gas Detectors Gas detectors are essential safety equipment that helps to maintain a safe work environment and are vital for measuring toxic gases such as chlorine in locations where chlorine gas is stored, used, or may accumulate. Various industries use chlorine, including water treatment, chemical manufacturing, and swimming pools, and it poses significant health risks […]
What is a Fixed Gas Detector?

What is a Fixed Gas Detector?

The evolution of toxic gas detectors is rooted in industrial safety, with milestones marking significant leaps in detection technology. In the early 20th century, electrochemical sensors were among the first devices designed to identify lethal gases in coal mines. The sensors relied on a chemical reaction between the toxic gas and an electrode, generating an electrical […]

Coming Clean on Chlorine Gas Safety

What is Chlorine? Chlorine gas (Cl2) is a dense, yellow-green gas that has a distinctive, irritating odor that is similar to bleach and is almost instantly noticeable even at very low concentrations. While Cl2 is not flammable, it may react explosively when exposed to other gases, including acetylene, ether, ammonia, natural gas, and hydrogen, among […]

Recycling and Reusing Wastewater

Recycling and Reusing Wastewater

When one hears the word “recycling”, does wastewater typically come to mind? Probably not. Most of us think about recycling paper products, plastic bags, aluminum foil, and water bottles.  But what happens to the wastewater we create when we bathe, wash the dishes, do laundry, and flush the toilet? According to the International Water Association, […]
Gas Detectors Can Ensure Chlorine Safety in Swimming Pools

Gas Detectors Can Ensure Chlorine Safety in Swimming Pools

In April 2019, six people became sick after being exposed to chlorine gas at a hotel pool in India, because one of the chlorine gas cylinders, which had been stored improperly, began to leak, exposing swimmers to chlorine gas.  In June 2019, some 50 pool patrons became ill after a pump malfunction leaked chlorine gas […]
